ELECTRIC STEERING NOISY WHEN USED WITH VEHICLE STATIONARY

The cusomter complains of noise from the electric steering with the vehicle stationary, with the ignition off and/or whilst driving

1	CHECK ON TYPE OF NOISE	All OK	Problems met	Operation
		Results of the tests
	With the system not activated (ignition OFF), check the type of noise reported	Continue to Step 2	Noise similar to rubbing plastic.	Continue to Step 5
2	CHECK ON TYPE OF NOISE	All OK	Problems met	Operation
	With the system activated (ignition ON), check the type of noise reported	Continue to Step 8	Electric type noise (buzzing)	Continue to Step 4
			Noise similar to a click	Continue to Step 6
			Noise similar to reverse rotation of the steering wheel.	Continue to Step 7
			Noise similar to high pitched creaking.	Continue to Step 3
			Noise similar to a series of bangs during rotation.	Replace the EPS system Op. 4110D20 Continue to Step 3
3	MECHANICAL CHECK	All OK	Problems met	Operation
	Check the condition of the EPS electric motor rear bearing.	Continue to Step 8	The bearing is intact.	Replace the EPS system Op. 4110D20
	Check the condition of the EPS electric motor rear bearing.	Continue to Step 8	The bearing is damaged	Replace the system electric motor Op. 4110D30
4	CHECK ON INTENSITY OF NOISE	All OK	Problems met	Operation
	Check the intensity of the noise (slight noise that cannot be heard on the passenger side is normal for an EPS system).	Continue to Step 5	The noise is loud	Replace EPS system electric motor Op. 4110D20
5	INTERFERENCE CHECK	All OK	Problems met	Operation
	With the system not activated (ignition OFF), check: interference of the steering wheel with the surrounding plastic parts. interference of the steering wheel and/or driver's airbag with the surrounding parts. interference of the steering column with the surrounding plastic parts. interference between the lower forks connecting the steering box and the floor carpet.	Continue to Step 8	The steering wheel is in contact with the upper and/or lower trim.	Reposition the steering column trim.
			Noise noticed from the steering wheel and/or one of its components	Restore the correct operation of the defective component.
			The steering column and/on steering column switch unit is in contact with the upper and/or lower trim	Reposition the steering column switch unit and/or steering wheel cover
			The fork is rubbing on the floor and/or carpet	Reposition the vehicle floor covering
			Noise noticed from inside the electric steering	Replace the EPS system Op. 4110D20
6	FORK TIGHTENING CHECK	All OK	Problems met	Operation
	Check that the lower fork nut is correctly tightened on the steering box pinion	Continue to Step 8	Tightening not correct	Restore the correct tightening
7	STEERING WHEEL OSCILLATION CHECK	All OK	Problems met	Operation
	Check the type of steering wheel oscillation	Continue to Step 8	The fault occurs when the steering wheel oscillation is slight	Replace the EPS system insulator (flexible coupling)
	Check the type of steering wheel oscillation	Continue to Step 8	The fault occurs when the steering wheel movements are sudden, similar to emergency manoeuvres	Replace the EPS system intermediate shaft
8	Continue as instructed by the tester	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	Fault persists	Replace the EPS system Op. 4110D20
